WASHER OR GASKET CUTTER.

PECIFICATION forming part of Letters Patent No. 352,139, dated November 9, 1886.

Application filed July 30, 1886. Serial No. 209,579. (No model.)

To all whom it may concern.-

Be it known that I, JOHN LEUENBERGER, a resident of the town of Camden, Preble county, and State of Ohio, have invented certain new and useful Improvements in Washer or Gasket Gutters, of which the following is a specification. i

The various features of my invention, and

the advantages arising from their use, will be apparent from the following description and claims. I

In the accompanying sheet of drawings, forming part of this'specification, Figure 1 is a side elevation of a device illustrating my in vention, the diameter of aizle to which the calipers are set being shown in dotted lines at the foot of said device.

lower part of theshank, sliding bar, calipers, and shank of knives being shown in section, and illustrating the connection of said knives and calipers to said sliding bar.

A represents the shank, the upper end of which is of a suitable shape to engage with an ordinary augerbit or other implement, and at the lower end of said shank A, and constituting a partof same, is the point or pointer D. The lower end of this shank, just above the pointer D, is made hollow to suit the coufiguration of the sliding bar B, and in said hollow or space said bar slides when the calipers arelbein g adjusted to the sized axle or other object for which a gasket or washer is desired to be cut. At this point of the shank is preferably attached a thumb set-screw, S, for hold-- ing the slidingbar in position after it has been set for any given dimension of washer or gasket to be cu't.

On one side of the shank A, preferably" about midway its length, is cast or otherwise united to it one part, 0, of the calipers. The other part, 0, of tlie calipers is attached to the. part 0, preferably by a screw-connection, as shown, but may be connected by a rivet or other device that will allow of pivotal play of the part 0. This part 0 of the calipers is preferably made in the shape shown in the drawings, the lower end of which is in the form of a graduating-arc. In this are is cut or forged out a graduating-slot, as 0, through which is passed the bolt or screw-stud B which screw or bolt is fastened in the end of the sliding bar B, preferably as shown. In that end of the slid- Fig. 2 is a view in eleva tion of the same dimensions as in Fig. 1, the

1 ing bar B which is opposite the end to which the arc of the calipers is attached a slot, B, is present, in which the shank of knife D is made adjustable to out different widths of gaskets or washers. The knife D is preferably rigidly attached to the sliding-bar B at theinner end of theslot B. The knife D is, after or gasket to be cut, firmly attached to the bar B in the slot B, preferably, as shown, by means of a thumb-screw, d, screwed on the upper part of the shank d of the knife. By turning this thumb-screw d, the shoulder at of the knife D is brought up tight against the under surface of the sliding bar B, and thus serves to keep this knife in position.

The advantage of this cutter over those now in use is at once apparent. In the cutters heretofore made the dimensions of the object for which a washer" or gasket is to be cut must first be taken by a rule or similar device, and then the knives must be set by loosening the thumb-screws and taking the dimensions from the rule, and setting the knives correspondingly with the center-pin, which requires considerable time and delay, andisoften unsatisfactory. In my device all that is required in order to cut a washer orgasket of the desired dimension is simply to loosen the thumb-screw S, and place the points of the calipers on opposite sides of the diameter of the object for which a washer or gasket is required,as shown in dotted lines in Fig. 1, and then tighten the thumb screw S, the construction and position of the calipers and graduating-slot G in relation to the sliding bar and pointer D being such that, when the dimension of the object for which a washer is to be cut is taken, the distance from knife D to pointer D represents one-half the diameter of the washer to be cut.

When desired, my device may be advantageously employed in cutting circular disks, and in,that case all that is necessary is simply to dispense with the adjustable knife B, the diameter of said disk being determined the same as in cutting washers.

What I claim as new and of my invention, and desire to secure by Letters Patent, is

1. In a washer or gasket cutter, the combination of main shank A, caliperslO 0, sliding substantially as and for the purposes specified.
